Spontanious, Irrelevant, Random, Reckless, some would say ghetto but...humble, not real gangsters. Often seen making fun of the real trill community. Can be black, white, puerto rican, asian or any other monster/creature. Most often seen on the race track or jumping mats/pits or pole vault area.

Those track girls are such Trill Rats.

Are you a trill rat? I wanna trill rat. I gotta trill rat, I gotta trill rat.
